NKR's right to self-determination, its overland communication with Armenia and international security guarantees should never be doubted, said Hovhannes Margaryan, member of Orinats Yerkir party.

"This is our party's principles, which are also precisely mentioned in the Madrid Document," he said, adding that Nagorno Karabakh should join the talks.

"Madrid principles were discussed by Orinats Yerkir party in detail and we fully support the position of RA President," Margaryan said.
